CVE-2026-30892: 
NixOS vulnerability analysis and mitigation

crun is an open source OCI Container Runtime fully written in C. In versions 1.19 through 1.26, the crun exec option -u (--user) is incorrectly parsed. The value 1 is interpreted as UID 0 and GID 0 when it should have been UID 1 and GID 0. The process thus runs with higher privileges than expected. Version 1.27 patches the issue.
